Re: 25 seconds of fuel
The ALSJ has:
102:45:31 Duke: 30 seconds (until the 'Bingo' call).
102:45:40 Aldrin: Contact Light.
The "Bingo" moment was the last possible moment for an abort. An abort required five seconds of full thrust from the descent module before it could jettisoned and the ascent module take over. At hover thrust those five seconds would be an additional twenty seconds. So the Commander *could* have decided to carry on past the bingo point if he was within seconds of touch down.
